Web1 mrt. 2024 · Each nucleotide in DNA contains one of four possible nitrogenous bases: adenine (A), guanine (G) cytosine (C), and thymine (T). Adenine and guanine are classified as purines. The primary structure of a purine is two carbon-nitrogen rings. Cytosine, thymine, and uracil are classified as pyrimidines which have a single carbon …
Web30 jan. 2024 · The pyrimidines (cytosine, uracil, and thymine) only have one single ring, which has just six members and two nitrogen atoms. Because purines are essentially pyrimidines fused with a second ring, they are obviously bigger than pyrimidines. This size difference is part of the reason that complementary pairing occurs. DNA: Complementary … WebAnswer: The pyrimidines, cytosine and uracil, are smaller and have a single ring, while the purines, adenine and guanine, are larger and have two rings. C. The purines, adenine and guanine, are larger and have two a one-ringed structure, while the pyrimidines, thymine and cytosine, have two rings and are smaller. Advertisement. noviemaeociel.
